Abstract
in 3.5 wt% NaCl solution, which are significantly lower than that of ultra-high-purity Mg and all Mg alloys reported thus far. The outstanding corrosion resistance is attributed to inhibition of cathodic water reduction kinetics, impurities stabilizing and a protective surface film induced by Ca micro-alloying. Combined with the environmental benignity and economic viability, Ca micro-alloying renders huge feasibility on developing advanced Mg-based materials for diverse applications.
